That is, the division into the first member 12a and the second member 12b is performed in order to maintain the ease of operation and the structural strength because the members are pressed in one direction at the time of heat and pressure pressing.

The first member 12a and the second member 12b are formed by dividing the support member 12 into halves in the longitudinal direction and have inclined portions 13, supporting portions 14, engaging portions 15, and ribs 15c ) Is divided into two halves.

The horizontal support member 16 may be installed in such a manner that the inclined portions 13 of the different support members 12 are connected to each other. As shown in Fig. 1A, the horizontal supporting member 16 can be fixed to at least two inclined portions 13 so as to be perpendicular to the inclined portion 13 or the bottom member 11. As shown in Fig. The horizontal support member 16 can be installed to a length reaching two bottom members 11 provided at both ends and can be installed so that two or more are fixed to one support portion 14 at regular intervals, It is not. The horizontal support member 16 may be made of the same or similar material as the bottom member 11 or the support member 12. [

In addition, a groove 21 having a circular cross section can be formed on the inner edge of the support portion 20a. The formation of the groove 21 as described above prevents the lower end edge of the solar cell module S contacting the support portion 20a from being broken when the end portion of the solar cell module S is mounted on the support portion 20a .

The solar power generating module S is constructed such that a central portion or an upper end portion of the back surface is coupled to the horizontal supporting member 16 and a separate bracket 18 is formed between neighboring solar power generating modules S, So that both ends of the module S can be constrained to be coupled to the horizontal supporting member 16. [

FIG. 5 is an enlarged view showing a state of engagement of the solar cell module S according to the present invention.

5, the bracket 18 is provided with a coupling channel 18a having a U-shaped cross section and a pressing piece 18b having a shape bent outward in both directions at the upper end of the coupling channel 18a, And the coupling channel 18a is coupled to the horizontal supporting member 16 so that the pressing piece 18b presses both side ends of the solar power generating modules S on both sides .

In order to support the solar cell module S on the first floor fixing member 20 separately from the horizontal supporting member 16 when the solar cell module S is connected to the horizontal supporting member 16, The horizontal support member 16 which is located on the horizontal support member 16 fixes the solar power generation module S and supports the lower end portion of the solar power generation module S on the fixing member 20, So as to fix the solar module S in a more stable manner.

Since only one horizontal supporting member 16 is used for installation of the solar module S, it is possible to reduce the size of the supporting member 12 and reduce its own weight.

A bottom plate 17 provided on the bottom member 11 may be provided to form a passage for maintenance or repair of the solar module S. [

3 is a view showing an embodiment of a bottom plate 17 of a floating structure 10 according to the present invention.

3, a second bottom fixing member 19, a second bottom fixing member 19, and a first bottom fixing member (not shown) are disposed parallel to the first bottom fixing member 20 at a predetermined interval, 20 may be additionally constructed.

The bottom plate 17 provided on the bottom member 11 forms a passage for maintenance or repair of the solar power generation module S. The bottom plate 17 may be installed at an arbitrary position in consideration of the convenience of maintenance or repair, but it is preferably provided on the entire surface of the solar cell module S so as to extend in a direction perpendicular to the longitudinal direction of the bottom member 11 Can be installed. The width of the bottom plate 17 can be any size that allows human walking, and can be made of a lightweight material having a certain strength such as, for example, a wire mesh or plastic. The bottom plate 17 can be installed on top of the second floor fixing member 19 and the first floor adjusting member 20 such as, for example, H-shaped steel. At this time, the second floor fixing member 19 is configured to maintain a predetermined gap with the first floor fixing member 20, and the second floor fixing member 19 and the first floor fixing member 20 The plate 17 can be fixedly constructed. As described above, by utilizing only the first bottom floor fixing member 20 and adding only one second floor bottom fixing member 19, the amount of the installed members can be minimized.

The bottom member 11, the horizontal support member 16, the first bottom fixing member 20 and the second bottom fixing member 19 may be made of a fiber-reinforced composite material and may be manufactured in a pearl-truing manner.

The members of the floating structure are superior to the steel materials in terms of material performance and are excellent in corrosive environments such as salt and harmful environment and can be used semi-permanently. Fiber Reinforced Polymeric Plastic, FRP). Fiber reinforced composites are composed of resin and reinforcing fibers. Resin transmits stress (load) between reinforcing fibers, prevents buckling of reinforcing fibers, protects reinforcing fibers from harmful environments, protects reinforced fibers from mechanical wear, Resistance and the like, and epoxy, polyester, vinyl ester, phenol and the like can be used. Reinforcing fiber is a main element to resist the load, and properties vary greatly depending on the type and arrangement of the reinforcing fiber. As the reinforcing fiber, carbon fiber, aramid fiber, glass fiber, or the like can be used. Methods for producing the fiber-reinforced composite material include pearl truing, filament winding, and hand lay up. In the present invention, the cross-sectional shapes of the respective members described above are produced by the pearl truss method. The pearl truing method is produced through a die that determines the cross-sectional shape by drawing and can be produced indefinitely without limitation in the longitudinal direction, and the reinforcing fiber is arranged mainly in the longitudinal direction.

The structure having the structure as described above can be kept floated on the water surface by the float 30.

The float 30 may have various overall shapes and may be fixed to the bottom of the bottom member 11.

FIG. 6 is an exploded perspective view of a float according to an embodiment of the present invention, and FIG. 7 is a sectional view of a float applied to FIG.

6 and 7, the float 30 according to the present invention may include a lower bucket 320, an upper lid 330, and a resin foamed block 340. The lower bucket 320 and the upper lid 330 are joined together to form an outer cylinder.

Since the float 30 is formed as a box-like highly durable floating body and is installed at a constant interval below the floor member 11 as described above, the float 30 It is easy to install the float 30 because the float 30 is installed at a lower part of the bottom member 11 at regular intervals and it is very easy to partly replace the float 30, There is no need for a separate member for reducing the amount of adherend.

The lower bucket 320 is composed of a chamber 322 of a predetermined size opened at the top and a flange 323 for bonding formed at the opening side. As shown in FIG. 6, the lower bucket 320 has an elliptical cross section whose periphery has a slope at a predetermined angle? Relative to the bottom surface 321, and whose cross section increases in the upward direction from below.

When the lower buckle 320 is formed in an elliptical shape, the effect of the wave can be minimized.

Thus, the lower bucket 320 becomes smaller in cross section downward and larger in cross section than the lower bucket 320, and is less influenced by algae. In addition, the lower bucket 320 can be easily balanced even when it is moved by the waves, thereby inducing the floating structure 10 to float in a stable posture on the water surface. In addition, as the lower bucket 320 descends below the water surface, the buoyant force increases sharply, so that the restoration speed at which the float 30 floats up to the water surface is quickened, and the stable facility can be quickly stabilized without delay.

The lower bucket 320 may be made of a metal plate coated to prevent corrosion, but it is preferable that the lower bucket 320 is made of a hard resin material having a smaller specific gravity than water and excellent formability. More preferably, it can be made of fiber reinforced plastic (FRP) which is lightweight and excellent in strength and durability.

At this time, the size of the lower bucket 320 is made considering the size of buoyancy. That is, the larger the weight of the floating structure, the larger the size of the lower bucket 320 can be.

The joining flange 323 is formed along the opening of the lower bucket 320. Therefore, since the lower bucket 320 is formed according to the shape of the upper surface of the lower bucket 320, the elliptical flange is formed in the lower bucket 320.

The upper cover 330 is made of the same material as the lower bucket 320. The upper lid 330 is engaged with the lower bucket 320 to seal the chamber 322. The upper cover 330 has a cover flange 331 of the same shape to be engaged with the opening of the lower bucket 320 on the lower surface. At least one frame fixing positioning groove 332 for positioning the environmentally-friendly floating structure 10 for installing the solar module is formed on the upper surface of the upper cover 330. The frame fixing positioning groove 332 is concave so that the bottom member 11 of the floating structure 10 is freely seated so that the cross section has a rectangular shape and the depth of the groove is equal to the height of the bottom member 11 .

Therefore, when the floating structure 10 is installed in the frame fixing positioning groove 332 of the upper cover 330 as shown in FIG. 8, the frame fixing positioning groove 332 functions as a separation preventing tongue. Accordingly, the binding force between the floating structure 10 and the float 30 is increased, and stable floating installation of the floating structure 10 on the water surface is possible.

That is, since the elliptical float 30 is coupled to the bottom member 11 so that its long axis is orthogonal to the bottom member 11, the frame fixing positioning groove 332 is formed by the arrangement of the bottom member 11 of the floating structure 10 In a direction orthogonal to the long axis of the float (30) according to the structure.

The reason why the long axis of the float 30 is orthogonal to the bottom member 11 is that the distance between the float 30 is short so that the moment between the float 30 in the whole structure is reduced .

The upper cover 330 may be joined with a bolt, a nut or the like by applying an adhesive between the lower bucket 320 and the flange. At this time, a gasket may be added to increase the sealing between the upper cover 330 and the lower bucket 320.

On the other hand, a resin foamed block 340 is installed on the joint surface of the lower bucket 320 and the upper lid 330 to eliminate the risk of leakage. The resin foamed block 340 is hermetically sealed between the upper cover 320 and the lower bucket 320. Therefore, the resin foamed block 340 may be formed in the same shape as the chamber 322 of the lower bucket 320. The resin foamed block 340 may be made of styrofoam or urethane foam.

When the lower bucket 320 and the upper lid 330 are made of fiber-reinforced plastic, the float 30 constructed as described above shows high durability. Even if a hermetic seal failure occurs at the junction between the lower bucket 320 and the upper lid 330, buoyancy is continuously generated by the resin foam block 340, so that flooding of the floating structure 10 is prevented So that a stable injury can be maintained.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the above teachings. will be. The invention is not limited by these variations and modifications, but is limited only by the claims appended hereto.
